Is that 100,000 dead birds every day, every week or every year? Cats kill many times that many birds every year.

Killing birds and other flying critters isn't much of a reason to oppose windmills. Better reasons include the fact that windmills are an expensive and unreliable way to generate electricity in most of the country. You'd never see many big windmills if it weren't for the heavy subsidizies.

It is an annual estimate (i.e. extrapolation from a sample) for the United States. Cats are not included because they are not relevant to anthropogenic effects. Other than, perhaps, through causing an artificial concentration of cats.

You're right. That is not the reason to offer general criticism of the technology. The primary issue is, as you have stated, that the technology cannot reliably produce energy with reasonable isolation from the environment. I only repeat it to remind people that "green" technology is a marketing term, which does not mitigate risk as reported, and this specific consequence is a readily observable and quantifiable phenomenon to establish its fraudulent presentation.

Also, it is relevant within this context and it has humorous implications.

I encourage and tend to have quite a few nesting families on my property every summer. I'm amazed at the number of parasites and predators that take their toll. Crows, hawks, foxes, raccoons - it's a genocide. And the nests themselves are teaming with parasitic blood sucking mites by the thousands. Let 'em have their butts. Life is hard enough.
